Description
Technical Field
The utility model belongs to the technical field of medical instruments, and particularly relates to a bipolar surgical instrument electrode tip.
Background
The current surgical devices for cutting hemostasis are mainly divided into two categories: one type uses mechanical energy to achieve a cutting hemostasis effect, wherein the representative is an ultrasonic knife; another type of device uses high frequency current to generate heat through tissue to achieve hemostatic effect, such as bipolar coagulation knife, monopolar electric hook, monopolar electric knife, etc. For doctors, small operations with small difficulty and short time consumption, and instruments such as a multi-purpose electric hook for doctors, and large and medium operations with large difficulty and long time consumption, the doctors use more ultrasonic knives and bipolar coagulation knives. Since the ultrasonic scalpel is available and popularized earlier, most doctors are inclined to use the ultrasonic scalpel or an operation method similar to the ultrasonic scalpel when performing surgery, and the bipolar coagulation scalpel needs a certain familiar process in the operation method and is relatively less in use. However, the former two also have certain disadvantages.
Defects and deficiencies of ultrasonic knives:
1) due to its own working principle, the tissue cutting speed is slow.
2) The mechanical vibration of the cutter head causes the tissue to splash, and particularly the tumor cells risk the tissue to splash and replant.
3) Are vulnerable to breakage when exposed to hard materials or tissues (e.g., bone or graspers).
4) Due to its own working principle, coagulation is poor in the liver tissue cutting process.
Defects and deficiencies of bipolar coagulation knives:
1) there are different manipulations, and it is necessary to learn a certain skill when using the first time.
2) The blood coagulation effect in the cutting process is different due to different manipulations, and the initial use is difficult to master.
3) Too fast cutting easily results in separation of blood on both sides during cutting without coagulation, resulting in bleeding.
SUMMERY OF THE UTILITY MODEL
In order to solve the above technical problems, it is an object of the present invention to provide a bipolar surgical instrument tip which facilitates an improved coagulation effect during cutting of tissue.
In order to achieve the technical purpose, the utility model adopts the following technical scheme: the bipolar surgical instrument electrode tip comprises an upper electrode and a lower electrode which can be opened and closed relatively, grooves are respectively arranged on the opposite surfaces of the upper electrode and the lower electrode, a semiconductor cutter is embedded in one groove, the semiconductor cutter can be pressed into the other groove after the upper electrode and the lower electrode are closed relatively, and gaps are respectively formed between the upper electrode and the lower electrode and positioned on two sides of the semiconductor cutter.
As a preferred technical scheme, the groove is a rectangular groove.
